Contours of Alternative Policy Making in Venezuela
(Sage Publications Inc, 2014) Orhangazi, Özgür
The economic policies of the Venezuelan government in the last decade represent a significant departure from neoliberal orthodoxy. This departure consists of a focus on greater national autonomy, a return to some of the macroeconomic policies of earlier eras, and increased state involvement in the economy through interventions and social programs. While these policies have resulted in improved social indicators, they also have provided space for a set of "transformative" initiatives, including experiments with worker co-management, cooperatives, and participatory planning, all of which seek alternatives to the capitalist organization of the economy. Although the Venezuelan experience could be considered sui generis, especially with the economy's dependence on oil, a critical evaluation of the policies implemented in Venezuela would contribute to discussions on the alternatives to both neoliberal policies and capitalism in general. This paper provides an analysis of the break with neoliberal economic policies and of the transformative initiatives, as well as an evaluation of their achievements together with a discussion on their likely future path.

Time-Varying Fairness Concerns Delay and Disagreement in Bargaining
(Elsevier Science, 2018) Karagozoglu, Emin; Keskin, Kerim
We study an alternating-offers bilateral bargaining game where players may derive disutility from accepting shares below what they deem as fair Moreover we assume that the values they attach to fairness (i.e. their sensitivity to violations of their fairness judgments) decrease over time as the deadline approaches. Our results offer a new explanation to delays and disagreements in dynamic negotiations. We show that even mutually compatible fairness judgments do not guarantee an immediate agreement. We partially characterize conditions for delay and disagreement and study the changes in the length of delay in response to changes in the model parameters. (C) 2018 Elsevier B.V.

A Dynamic Game Theory Model for Tourism Supply Chains
(Sage Publications, 2021) Keskin, Kerim; Ucal, Meltem Şengün
This article contributes to the game-theoretic analysis of tourism supply chains. We start with a baseline model including three types of agents: (a) one theme park, (b) multiple accommodation providers, and (c) multiple tour operators. We investigate the strategic dynamics (i.e., collaboration and competition) embedded in a market with two different tourism supply chains, and then we extend our model to an infinite-horizon repeated game arguing that agents would face the same decision problem in each week of every holiday season in each year. We show how agents in a tourism supply chain end up with higher profits in any given period of a repeated game compared with their profits in the static version of the game.

Competition and Monopoly in the U.s. Economy: What Do the Industrial Concentration Data Show?
(Sage Publications, 2021) Davis, Leila; Orhangazi, Özgür
A recent series of academic studies, think-tank reports, and news articles shows widespread attention to rising industrial concentration and market power in the U.S. economy. In this paper, we focus on concentration in the U.S. nonfinancial corporate sector to make three contributions to the literature. First, we use examples from the debate on industrial concentration to show that there are often-divergent predictions in the theoretical literature surrounding the expected consequences of concentration and monopolization for nonfinancial firms. Second, we use industry-level concentration data to describe recent trends in average concentration. We show that, while concentration increases across the majority of industries after the late 1990s, the retail and information-services sectors are particularly key for understanding recent trends in average industrial concentration. Third, we link our industry-level analysis with firm-level data to describe the relationship between industrial concentration and nonfinancial corporations' profitability, markups, and investment. Consistent with the ambiguities in the theoretical literature, we find that these relationships are not uniform: while some highly concentrated industries confirm standard expectations with high markups, high profitability, and low investment rates, other highly concentrated industries earn lower-than-average markups and profits, suggesting that - in some industries - increased concentration and intensified competition may go hand in hand.

Identifying City Differences in Perceived Group Discrimination Among Second-Generation Turks and Moroccans in Belgium
(Routledge Journals Taylor & Francis Ltd, 2015) Alanya, Ahu; Baysu, Gülseli; Swyngedouw, Marc
This study investigates the effects of city context on the levels and predictors of perceived group discrimination (GD) among Turkish and Moroccan second-generation immigrants in Belgium. Based on the Integration of the European Second-generation (TIES) data we address two main questions: (1) Are there significant differences in the levels of perceived GD between the two cities in Belgium (Antwerp and Brussels) within each immigrant group? (2) Who perceives more GD within each city? To answer these questions possible composition effects should be controlled. Accordingly we use propensity-score matching to make second-generation immigrant samples from the two cities reasonably comparable with respect to socio-demographic characteristics. Concerning the first research question we find that after propensity-score matching the Turkish second-generation perceive more GD in Antwerp than in Brussels. For the Moroccan group however the city differences in perceived GD are no longer significant after matching. With regards to the second research question we find that those who are more socio-economically integrated and those who perceive more threat in their city are more likely to perceive GD.

Detecting Structural Changes Using Wavelets
(Academic Press Inc Elsevier Science, 2015) Yazgan, M. Ege; Ozkan, Harun
We propose a powerful wavelet method to identify structural breaks in the mean of a process. If there is a structural change in the mean the sum of the squared scaling coefficients absorbs more variation leading to unequal weights for the variances of the wavelet and scaling coefficients. We use this feature of wavelets to design a statistical test for changes in the mean of an independently distributed process. We establish the limiting null distribution of our test and demonstrate that our test has good empirical size and substantive power relative to the existing alternatives especially for multiple breaks.

Secondhand Smoke in Waterpipe Tobacco Venues in Istanbul Moscow and Cairo
(Academic Press Inc Elsevier Science, 2019) Moon, Katherine A.; Magid, Hoda; Torrey, Christine; Rule, Ana M.; Ferguson, Jacqueline; Susan, Jolie; Sun, Zhuolu; Abubaker, Salahaddin; Levshin, Vladimir; Çarkoğlu, Aslı; Radwan, Ghada Nasr; El-Rabbat, Maha; Cohen, Joanna E.; Strickland, Paul; Navas-Acien, Ana; Breysse, Patrick N.
Objective: The prevalence of waterpipe tobacco smoking has risen in recent decades. Controlled studies suggest that waterpipe secondhand smoke (SHS) contains similar or greater quantities of toxicants than cigarette SHS which causes significant morbidity and mortality. Few studies have examined SHS from waterpipe tobacco in real-world settings. The purpose of this study was to quantify SHS exposure levels and describe the characteristics of waterpipe tobacco venues. Methods: In 2012-2014 we conducted cross-sectional surveys of 46 waterpipe tobacco venues (9 in Istanbul 17 in Moscow and 20 in Cairo). We administered venue questionnaires conducted venue observations and sampled indoor air particulate matter (PM2.5) (N=35) carbon monoxide (CO) (N=23) particle-bound polycyclic aromatic hydrocarbons (p-PAHs) (N=31) 4-methylnitrosamino)-1-(3-pyridy1)-1-butanone (NNK) (N-43) and air nicotine (N=46). Results: Venue characteristics and SHS concentrations were highly variable within and between cities. Overall we observed a mean (standard deviation (SD)) of 5 (5) waterpipe smokers and 5 (3) cigarette smokers per venue. The overall median (25th percentile 75th percentile) of venue mean air concentrations was 136 (82 213) mu/m(3) for PM2.5 3.9 (1.7 22) ppm for CO 68 (33 121) ng/m(3) for p-PAHs 1.0 (0.5 1.9) ng/m(3) for NNK and 5.3 (0.7 14) mu g/m(3) for nicotine. PM2.5 CO and p-PAHs concentrations were generally higher in venues with more waterpipe smokers and cigarette smokers although associations were not statistically significant. Conclusion: High concentrations of SHS constituents known to cause health effects indicate that indoor air quality in waterpipe tobacco venues may adversely affect the health of employees and customers.

Ethnic Fractionalization Conflict and Educational Development in Turkey
(Pergamon-Elsevier Science Ltd, 2019) Oyvat, Cem; Tekgüç, Hasan
We examine the impact of ethnic fractionalization and conflict on limiting the educational development in Southeastern Turkey. Our estimates show that although the armed conflict in the region did not directly hinder education investments it reduced school enrolment rates at middle and high school levels while increasing enrolment at the primary school level. Moreover we show that provinces with higher percentages of Kurdish population received less education investment. These results suggest that the neglect of Kurdish areas is an important factor behind Southeastern Turkey's educational underdevelopment while land inequality and the armed conflict had mixed effects on education in the region.

Turkey's Energy Strategy and the Middle East: Between a Rock and a Hard Place
(Routledge Journals Taylor & Francis Ltd, 2011) Han, Ahmet Kasım
This article examines Turkey's energy relations with the Middle East from a perspective of opportunities and limitations brought about by the structure of Turkey's general energy relations. As Turkish foreign policy and energy strategy become increasingly integrated Turkish-Middle East energy relations offer a solid test case on the soundness and applicability of not only Turkey's energy strategy but also for the success of Turkey's foreign policy during the last decade. Analyzing Middle East energy and the structure of Turkey's energy (im)balances this article goes on to explore Turkey's energy relations with individual Middle East countries and questions the results achieved. While doing so it also puts and evaluates Turkey's energy strategy within the context of Turkish foreign policy. It argues that as the result of diverse effects and influences of policies observed by Turkish officials as well as an array of structural factors the gains of Turkey's energy strategy and its future success remains questionable while the case of energy strategy provides a telling case on the success of Turkish foreign policy.

Market Power in Cee Banking Sectors and the Impact of the Global Financial Crisis
(Elsevier Science Bv, 2014) Efthyvoulou, Georgios; Yıldırım, Canan
The aim of this study is to undertake an up-to-date assessment of market power in Central and Eastern European banking markets and explore how the global financial crisis has affected market power and what has been the impact of foreign ownership. Three main results emerge. First while there is some convergence in country-level market power during the pre-crisis period the onset of the global crisis has put an end to this process. Second bank-level market power appears to vary significantly with respect to ownership characteristics. Third asset quality and capitalization affect differently the margins in the pre-crisis and the crisis periods. While in the pre-crisis period the impacts are similar for all banks regardless of ownership status in the crisis period non-performing loans have a negative effect and capitalization a positive effect only for domestically-owned banks.

Is China Integrated With Her Major Trading Partners: Evidence on Financial and Real Integration
(Vilnius Gediminas Tech Univ, 2010) Bilgin, Mehmet Hüseyin; Lau, Chi Keung Marco; Tvaronaviciene, Manuela
Applying the new panel unit root test developed in this paper we can overcome the pitfalls of old-fashioned panel unit root tests making it possible for researchers testing individual series for a unit root while taking contemporaneous cross-sectional dependence and structural break into account. The proposed test was used to investigate the status of financial and real integration of China Japan UK the European Union and the United States based on the empirical validity of real interest parity uncovered interest parity and relative purchasing power parity. We found strong evidence in favor of those parity conditions and hence concluded that financial and real integration between China and the other four countries was well established using the new developed panel unit root test while the traditional tests (either univariate or panel) fail to do so.

Measuring Energy Intensity in Japan: a New Method
(Elsevier, 2017) Zaim, Osman; Gazel, Tuğçe Uygurtürk; Akkemik, K. Ali
Energy intensity and energy conservation have been important pillars of energy policies in Japan. Recently the government has introduced new initiatives to enhance energy efficiency and reduce energy intensity. We analyze the energy intensity in Japan for the period 1973-2006 by proposing a new method which takes into account all other inputs used in production and corrects for the bias in the traditional energy intensity measure. We show that the traditional energy intensity measure has serious flaw. The traditional measure overestimates actual energy intensity before the mid-1980s and largely underestimates afterwards. It is found that aggregate energy intensity has risen remarkably from 1991 to 2001. The main cause of this rise is the rapid rise in energy intensity in manufacturing and energy sectors.

Can Law Impose Competition? a Critical Discussion and Evidence From the Turkish Electricity Generation Market
(Pergamon-Elsevier Science Ltd, 2014) Oğuz, Fuat; Akkemik, K. Ali; Göksal, Koray
Electricity markets have undergone regulatory reforms since the early 1980s around the world. Technical analyses of these reforms usually pay lip service to the influence of politics over regulatory processes. Existing studies examine certain aspects of the market such as demand pricing and efficiency and they touch upon political issues only passingly when economic models cannot provide sufficient explanation This approach problematically takes politics as an ad hoc variable. This study shows that electricity is intrinsically a 'political good' and argues that any meaningful reform effort should take institutions as the starting point rather than a residual. The argument that politics has to be an endogenous variable in any model aspiring to explain behavior in electricity markets is demonstrated in the paper. The evidence for the political good character of electricity is found by examining the Turkish regulatory reform for Which it is argued that there is not a satisfactory relationship between expected and realized gains.

Acculturation Attitudes and Social Adjustment in British South Asian Children: a Longitudinal Study
(Sage Publications Inc, 2013) Brown, Rupert; Baysu, Gülseli; Cameron, Lindsey; Nigbur, Dennis; Rutland, Adam; Watters, Charles; Hossain, Rosa; LeTouze, Dominique; Landau, Anick
A 1-year longitudinal study with three testing points was conducted with 215 British Asian children aged 5 to 11 years to test hypotheses from Berry's acculturation framework. Using age-appropriate measures of acculturation attitudes and psychosocial outcomes it was found that (a) children generally favored an integrationist attitude and this was more pronounced among older (8-10 years) than in younger (5-7 years) children and (b) temporal changes in social self-esteem and peer acceptance were associated with different acculturation attitudes held initially as shown by latent growth curve analyses. However a supplementary time-lagged regression analysis revealed that children's earlier integrationist attitudes may be associated with more emotional symptoms (based on teachers' ratings) 6 months later. The implications of these different outcomes of children's acculturation attitudes are discussed.

All the Dark Triad and Some of the Big Five Traits Are Visible in the Face
(Pergamon-Elsevıer Scıence Ltd, 2021) Alper, Sinan; Bayrak, Fatih; Yılmaz, Onurcan
Some of the recent studies suggested that people can make accurate inferences about the level of the Big Five and the Dark Triad personality traits in strangers by only looking at their faces. However, later findings provided only partial support and the evidence is mixed regarding which traits can be accurately inferred from faces. In the current research, to provide further evidence on whether the Big Five and the Dark Triad traits are visible in the face, we report three studies, two of which were preregistered, conducted on both WEIRD (the US American) and non-WEIRD (Turkish) samples (N = 880). The participants in both the US American and Turkish samples were successful in predicting all Dark Triad personality traits by looking at a stranger's face. However, there were mixed results regarding the Big Five traits. An aggregate analysis of the combined dataset demonstrated that extraversion (only female), agreeableness, and conscientiousness were accurately inferred by the participants in addition to the Dark Triad traits. Overall, the results suggest that inferring personality from faces without any concrete source of information might be an evolutionarily adaptive trait.

Engaging Nurses in Smoking Cessation: Challenges and Opportunities in Turkey
(Elsevier Ireland Ltd., 2018) Nichter, Mimi; Çarkoğlu, Aslı; Nichter, Mark; Ozcan, Seyda; Uysal, Mehmet Atilla
This paper discusses the training of nurses in smoking cessation as part of routine patient care in Turkey. Formative research was carried out prior to training to identify challenges faced by smokers when trying to quit. Site visits to government hospitals and cessation clinics were conducted to observe health care provider-patient interactions involving behavior change. Four culturally sensitive cessation training workshops for nurses (n=54) were conducted in Istanbul. Following training nurses were debriefed on their experiences delivering cessation advice. Challenges to cessation counseling included lack of time and incentives for nurse involvement, lack of skills to deliver information about the harm of smoking and benefits of quitting, the medicalization of cessation through the use of pharmaceuticals, and hospital policy which devalues time spent on cessation activities. The pay-for-performance model currently adopted in hospitals has de-incentivized doctor participation in cessation clinics. Nurses play an important role in smoking cessation in many countries. In Turkey hospital policy will require change so that cessation counseling can become a routine part of nursing practice incentives for providing cessation are put in place and task sharing between nurses and doctors is clarified. Nurses and doctors need to receive training in both the systemic harms of smoking and cessation counseling skills. Opportunities challenges and lessons learned are highlighted. (C) 2017 Elsevier B.V.

ObjectiveTo investigate public compliance with legislation to prohibit smoking within public buildings and the extent of tobacco smoking in outdoor areas in Turkey. Methods Using a standardized observation protocol we determined whether smoking occurred and whether ashtrays cigarette butts and/or no-smoking signs were present in a random selection of 884 public venues in 12 cities in Turkey. We visited indoor and outdoor locations in bars/nightclubs cafes government buildings hospitals restaurants schools shopping malls traditional coffee houses and universities. We used logistic regression models to determine the association between the presence of ashtrays or the absence of no-smoking signs and the presence of individuals smoking or cigarette butts. Findings Most venues had no-smoking signs (629/884). We observed at least one person smoking in 145 venues most frequently observed in bars/nightclubs (63/79) hospital dining areas (18/79) traditional coffee houses (27/120) and government-building dining areas (5/23). For 538 venues we observed outdoor smoking close to public buildings. The presence of ashtrays was positively associated with indoor smoking and cigarette butts adjusted odds ratio aOR: 315.9

Border Crossings Between Georgia and Turkey: the Sarp Land Border Gate
(Routledge Journals Taylor & Francis Ltd, 2017) Toktaş, Şule; Çelik, Nihat
The Sarp land border gate between Turkey and Georgia has become Turkey's gateway to the East in recent years. With a large number of individuals crossing every day it is also a labour gate where irregular Georgian immigrants cross the border for work in Turkey. In general border policies are constructed and reconstructed in a dynamic process in which economic security ethnopolitical geopolitical and cultural paradigms interact. The aim of this paper is to observe the complementary and conflicting relationship and negotiation process between economic and security paradigms in particular with a focus on the perceptions of the officers of the border administration and state bureaucracy at the local level. To this end field research was carried out consisting of interviews with Turkish state officials responsible for immigration and border crossing in the Sarp gate region. The article sheds light on the interaction between various agencies actors and stakeholders in border policymaking at the regional level. It also elaborates on the profiles both of incoming immigrants employed as irregular workers and of deportees. The results of the qualitative study show that the dominance of the economic paradigm that underlies the main framework of Georgia-Turkey relations overrides security concerns between the two countries thus necessitating a more flexible implementation of laws. The field research illustrates that implementation of laws and regulations at the local level varies and while some groups of irregular immigrants are allowed to work others are not and what is more are deported.

The Effect of Self-Concept Clarity on Discretionary Spending Tendency
(Elsevier Science Bv, 2016) Sarial-Abi, Gulen; Gurhan-Canli, Zeynep; Kumkale, Gökçe Tarcan; Yoon, Yeosun
Discretionary spending is an important indicator of economic well-being. However prior research is limited in empirically testing who is more likely to make discretionary purchases. To address this research gap this article suggests that those who have less clearly and confidently defined internally consistent and temporally stable self-knowledge (i.e. those who have low self-concept clarity [SCC]) have higher discretionary spending tendencies than high-SCC individuals. The results indicate that low-SCC individuals have higher discretionary spending tendencies because they are more likely to adopt avoidant coping strategies than are high-SCC individuals. This research further tests the effectiveness of elaboration on potential outcomes in reducing the discretionary spending tendencies of individuals with high- or low-SCC and demonstrates that it is effective only for high-SCC individuals. This article concludes with a discussion of the theoretical and managerial implications of the results. (C) 2015 Elsevier B.V. All rights reserved.

Evaluation of Secondhand Smoke Using Pm2.5 and Observations in a Random Stratified Sample in Hospitality Venues From 12 Cities
(MDPI, 2019) Kaplan, Bekir; Çarkoğlu, Aslı; Ergör, Gül; Hayran, Mutlu; Sureda, Xisca; Cohen, Joanna E.; Navas-Acien, Ana
Background: Turkey passed a law banning smoking in all indoor public places in 2008. In response to the indoor smoking restriction many smokers may have relocated to outdoor areas of venues. The aim of this study was to evaluate air pollution related to SHS exposure in indoor and outdoor areas of hospitality venues in 12 cities in Turkey. Method: In this cross-sectional study we evaluated hospitality venues in 12 cities in Turkey. In each visited venue we evaluated a pre-specified number of study locations such as the outdoor area of the main entrance indoor areas and patios or other outdoor dining areas completely or partially covered with window walls. We measured particulate matter 2.5 (PM2.5) in those areas. Results: The fieldworkers visited 72 randomly selected hospitality venues and measured PM2.5 concentrations in 165 different locations (indoor outdoor and patios) of those venues. Overall 2573 people were observed 909 of them smoking. The median (IQR) PM2.5 concentrations were 95 (39-229) g/m(3) indoors 25 (13-48) g/m(3) outdoors and 31 g/m(3) (16-62) in the patios (p < 0.001). After adjustment each additional smoker was associated with a 2% increase in PM2.5 concentrations in patio air (GMR (95% CI): 1.02 (1.00 1.05) and a 4% increase in indoor air (GMR (95% CI): 1.04 (1.02 1.05). Conclusions: There were unhealthy levels of smoking-caused PM2.5 concentrations not only indoors but also in the patios of hospitality venues. Legislative efforts to expand the smoke-free legislation to outdoor areas adjacent to indoor public places and an action plan to increase compliance with the smoke-free policy are urgently needed in Turkey.
